Control system for a traction wing
A control system for a traction wing or a surfing kite includes a bar that is gripped by a person carried in the wind by the wing or kite. Fixtures on the opposed ends of the bar are connected to respective lines that are attached to the wing. A central line attached to the wing passes through a hole located in the bar and divides into two lines that are connected to the user. A grip slides along the central line and the grip is biased toward the bar.
1. A control system for a traction wing comprising:
a bar having opposed first and second ends;
first and second fixtures respectively located at the first and second ends of the bar for connection to respective rear lines;
a transverse aperture through the bar;
a central line for connection to a user of the control system and passing through the transverse aperture, the central line bifurcating into two front lines;
at least one grip mounted on and sliding along the central line, the at least one grip being actuable to vary length of the central line for trim adjustment; and
resilient means for urging the at least one grip toward the bar.
2. The control system of claim 1 further comprising a mount for holding the at least one grip, the mount having an opening slidingly receiving the central line.
3. The control system of claim 2 wherein the resilient means comprises at least one resilient member.
4. The control system of claim 3 wherein the resilient means comprises a helical spring through which the central line extends.
5. The control system of claim 4 wherein the spring has a longitudinal end fixed to the mount.
6. The control system of claim 1 wherein the resilient means comprises at least one resilient member.
7. The control system of claim 6 wherein the resilient means comprises a helical spring through which the central line extends.
8. A control system for a traction wing comprising:
a bar having opposed first and second ends;
first and second fixtures respectively located at the first and second ends of the bar for connection to respective rear lines;
a transverse aperture through the bar;
a central line having a proximal end for connection to a user of the control system, wherein the central line passes through the transverse aperture, bifurcates into two front lines, and has a distal end opposite the proximal end;
a fitting located at the proximal end of the central line for connection to the user; and
resilient means located between the distal end of the central line and the transverse aperture for urging the bar toward the fitting.
9. The control system of claim 8 wherein the resilient means comprises a helical spring through which the central line extends.
10. The control system of claim 8 wherein the fitting comprises a harness loop.
11. The control system of claim 10 wherein the resilient means comprises a helical spring through which the central line extends.
